Description

technical field [0001] The invention relates to the technical field of three-phase asynchronous motor devices, in particular to a low-vibration three-phase asynchronous motor. Background technique [0002] The three-phase asynchronous motor is a type of motor that is powered by a 380V three-phase AC power supply (with a phase difference of 120 degrees) at the same time. Since the rotor and the stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a The difference rate, so it is called a three-phase asynchronous motor. [0003] The existing three-phase asynchronous motor will generate relatively large vibrations during operation. Due to the excessive vibration, it will cause damage to parts inside the motor and reduce the service life of the three-phase asynchronous motor. Contents of the invention [0004] Aiming at the defects in the prior art, the present invention provides a low-vibration thr...
